What this tool does
This tool converts a numeric amount into Chinese financial uppercase: 壹, 贰, 叁 … 元 (yuan), 角 (jiao), 分 (fen).
Invoices, receipts, contracts and IOUs in China require the amount written in Chinese uppercase, which is far harder to tamper with than plain digits. Writing it by hand is error-prone — one wrong character can invalidate the whole document, so this tool generates the correct form in one click.
How to use
- Enter the amount Type a number such as 1234.56. Thousands separators (1,234.56) and the ¥ sign are stripped automatically. At most two decimals are accepted.
- Choose a prefix By default the result is prefixed with 人民币 (RMB). Switch Prefix to “Uppercase only” if you want just the bare uppercase amount.
- Generate and double-check Press Generate to get the result, then copy or download it as a text file. Before filling in a cheque or contract, always compare the digits against the uppercase text — they must match exactly.
FAQ
What happens with more than two decimals?
The amount is rounded to the nearest cent — 1.005 becomes 壹元零壹分. For financial documents, enter the value already rounded to cents rather than relying on the tool’s rounding.
Can I convert negative numbers or letters?
No. Negative values, letters and scientific notation are rejected with a clear message, because they cannot appear on a valid invoice or contract.
What is the maximum amount?
The maximum is 999999999999.99 (about one trillion; 12 integer digits). Larger values are rejected. This range already covers everyday invoices and contracts.
Why is 整 appended at the end?
整 marks the end of the amount so that nobody can append extra characters. When both jiao and fen are zero (1000.00), the correct form is 壹仟元整.
Why does 0.5 become 伍角整 instead of 零元伍角?
When the yuan part is zero, financial convention omits 零元 and starts from the jiao place. This differs from cases like 壹拾元零伍分, where the yuan part is non-zero and a 零 must be inserted.
Can I paste the result straight into a document?
Yes, the format follows the standard financial convention. However, because invoices and contracts carry legal weight, always verify that the digits and the uppercase text agree; for large amounts have a finance or legal colleague review it.
Limits
This tool only performs a standard numeric-to-Chinese-uppercase conversion. It does not validate the business meaning of the amount and is not legal or financial advice.
Rounding is fixed to “round half up to the cent”. If your use case requires truncation instead, round the value yourself before entering it.
Maximum 999999999999.99. Negative values, letters, scientific notation and integer parts longer than 12 digits are not supported.
